Intel® Turbo Boost Technology

Recently intel has introduced many exciting feature to their Intel microarchitecture, one of such powerful technology is Intel Turbo Boost Technology which enables processor cores to run faster than the base operating frequency if it's operating below power, current, and temperature specification limits.

This technology provides a dramatic performance improvement in both multi-threaded and single threaded workloads along with Intel® Hyper-Threading Technology (Intel® HT Technology). Intel Turbo Boost Technology is only activated when the Operating System (OS) requests the highest processor performance state which means the amount of time a processor spend on Intel Turbo Boost Technology state is almost depend on the workload user needs and the operating environment.The maximum frequency of Intel® Turbo Boost Technology is dependent on the number of active cores.

several upper limits of boost technology are:
* Number of active cores
* Estimated current consumption
* Estimated power consumption
* Processor temperature

according to intel,it says that when user demand additional performance,

"the processor frequency will dynamically increase by 133 MHz on short and regular intervals until the upper limit is met or the maximum possible upside for the number of active cores is reached. Conversely, when any of the limits are reached or exceeded, the processor frequency will automatically decrease by 133 MHz until the processor is again operating within its limits."
